Step 1: Whisk the Wet Ingredients
Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper. In a large mixing bowl, aggressively whisk together the warm melted butter, brown sugar, and white sugar. Pro Tip: Whisk for at least 60 seconds until the mixture lightens in color and looks glossy. This helps dissolve the sugars and guarantees a chewy center.Step 2: Incorporate the Egg and Vanilla
Crack the room-temperature egg into the bowl and add the vanilla extract. Whisk gently just until the egg is fully incorporated. Actionable Tip: If you forgot to take your egg out of the fridge, place it in a bowl of warm water for 5 minutes before using.Step 3: Fold in the Dry Ingredients
Sprinkle the all-purpose flour, baking soda, and salt directly over the wet mixture. Using a rubber spatula, fold the ingredients together gently. Crucial Note: Stop mixing as soon as the last streak of flour disappears. Overmixing develops gluten, which leads to tough, cakey cookies rather than tender ones. (Want more baking science?

Pour in your chocolate chips and fold them into the cookie dough with 3 or 4 gentle strokes. Pro Tip: Reserve about a quarter cup of the chocolate chips. Pressing a few extra chips into the top of the dough balls right before baking gives them that professional, bakery-window appearance.Step 5: Scoop and Bake
Using a standard cookie scoop (about 1.5 tablespoons), drop the dough onto your prepared baking sheet, spacing them 2 inches apart. Bake on the middle rack for 9-11 minutes. The edges should be golden brown, but the centers will look slightly underbaked. Let them rest on the hot pan for 5 minutes before transferring to a wire cooling rack.
